But I think it is useful for every budoka at least to think about the seven virtues, after that.. everyone decides how he will behave himself. But in my humble experience it is always better for oneself to live with that virtues than without them..or against them

Eh. The problem that I always have with stuff like this is the "magic number" aspect. Let's have seven virtues, right, because seven is such a cool number! Then, after a while, people refer to them as the seven virtues, just as you've done above...as if there were no other virtues worth considering. Well, how about forbearance or restraint? How about abstinence? How about frugality, hard work or patience?
